Thanks! But no G’Mic, I used my own filter (script).
Freaky sharpening… freaky details… Same thing… 
Yes and no 
. I did my own implementation of the method described in the article of @patdavid because the G’Mic filter did not really reproduce what I did manually before. So, now I have a script filter that generates a new layer that produces the effect when combined with the background layer. The advantage is that I can apply a blur localy to the sharpening layer and, in this way, can limit the effect to certain regions.

Nice one to experiment with color grading. 
And I agree, there’s always something to photograph, no matter where you are. Patterns, shadows, reflections, colors,… Not everything tells a story or provokes questions like this one but IMO not everything has to.

@Thomas_Do : Sorry, my previous reply was meant as a bit of a jest. I did understand that I was wrong and that you created your own, GIMP based, script.
But, now that you described the script; That sounds like a nice one to have. Better then the one I initially, and wrongly, thought you used from G’MIC. I do remember reading and playing with Pat’s article and that you need to be really careful to not overdo it. Yours looks nice and conservative (for lack of a better word). I never went as far to make a script though.
Yep it is. I also applied a slight colour grading.
If you, or others, are interested I can post it here. But then maybe in an own thread, so it is easier to find?
I would be interested if you don’t mind sharing it.
Do make a separate topic, maybe you or others can add other scripts to it as well.
Thanks for the image. I was really feeling B&W for this one. The composition you chose I really liked so no cropping just a slight straighten based off of the metal boxes lid on the left. Color graded to my taste as I like a tone on my B&W images so I chose one I found pleasing for this presented composition.
dt 3.6 had to pull down and compile myself for image support really wanted to edit this image

That’s how I did in with GIMP, back in the day.
Interesting motif!
My edit is not realistic, as I again played with color contrasts to better separate foreground and background objects and get a bit more rough look. This gives the photo a little more three-dimensionality:

Very nice!
There are some nice overall touches (as usual), but I especially like what the tone equalizer 1 and colour calibration 1 modules do to the image.
Is removing the red from the no smoking sign intentional? Either way I like the effect, the red is somewhat of an unwanted eye catcher.
An attention point would be: Turn on defringe (have a look at the spokes).
This one is worth analyzing, especially when you are a darktable user!

No, I forgot to mask it. 
Very well observed! I screwed that up too. Normally the lens correction module does it, but your lens is not supported by lensfun.
Corrected version:

There’s something fishy going on at the moment with lensfun and Nikon’s Z series cameras in combination with F mount lenses. The lens is supported but isn’t picked up when using a Z6(II) (probably Z5/7 as well) body.
I see the same unwanted behaviour when using my other primes and zoom lenses. Only a generic length is picked up. This does not happen when I use these lenses with my D750.
I created a set of auto applied presets to fix it this way for the time being.
EDIT: This is also happens in RawTherapee.
Although this is a useful thing, in principle I find lensfun to be a shaky deal. Rawtherapee at least has the possibility to do the correction manually, which is a very big plus. In darktable this is only possible to a limited extent. Manual lens correction is one function I strongly miss in darktable.

The new chromatic aberration module has some interesting effects too in addition to correcting the aberrations if you use the blue channel as the guide I find it actually seems to perceptually sharpen the image in many cases
I noticed that one a while back. Haven’t played with it to be honest, spending most of my time using RawTherapee,with darktable on the back burner.
I’ll really have to put in some time/effort to have a more in-depth look at what it can do one of these days.
I’m like the reverse from you mostly in DT but coming back to RT or ART from time to time. RT is a great program but man …so so…many options
My Z 6 doesn’t seem to report my AF-P 70-300mm either. libraw has gotten better about lens nomeclature, but it’s apparently not finding what it needs to report the F mount lenses.
I’d be curious to see what Lightroom has; if it can figure out the mounted lens from the available metadata, then it’s in there somewhere…
